Industrial Solvents Limited mixes together three chemicals - A, B and C - in the ratio 3:2:1 to produce

Allklean, a specialised anti-static fluid. The chemicals cost 8, 6 and 3.90 per litre respectively.

In a period, 12 000 litres in total were input to the mixing process. The normal process loss is 5% of input

and in the period there was an abnormal loss of 100 litres whilst the completed production was 9500

litres.

There was no opening work-in-progress (WIP) and the closing WIP was 100% complete for materials and

40% complete for labour and overheads. Labour and overheads were 41 280 in total for the period.

Materials lost in production are scrapped.
